To all whom .it may concern Be it known that LVMoNnonR. KREAMER, a `citizen of the United States, residing at Aaronsbuig, in the county of Center and State of Pennsylvania, have invented eertain. new and useful Improvements in Valve Mechanism, of which the following is a specification.

My invention consists of an improvement in vvalve mechanism for liquid containers," and 'particularly for tank cars' or otherV ves.

sels subject-tothe usual strains of traffic.

'lhe ob'ects in view are to rovide a device of such `character which shall be. simple in construction, veasily .operated and locked or unlocked, with a minimum tendency ,to' breakage,.overcoming the disturbing effect of motion of the tank car, and having the features of advantage and `novelty hereinafter set forth. i 1 t y In `the drawings, showing Vcertain 'preferred embodiments ofthe. invention Fig. l is a cross section of a' tanlioarr showing one .form of the mechanism in position; n

In the drawings, 2 is the body of "a tank ear carried by the side sills 3 thereof, in the usual. way, and .having an outlet conduit et surrounding the valve seat 5 of usual con uniinpaired. Spindle 7 is connected Withth downward movement, byvv meaii'sof latera extending guides 18 formed with or attache' `rplest lform, lis provided with an uplne ,body of' the car proper and frame 8.

`bracket 8. The bracket 8 has an uppercrss member 19 and alower bridgepieoe 10 and pedestals 11 secured to the bottom of the tank by yrivetsor bolts ,12.l A cross bracing y., member 13 is framed intov the" top of braelie 65 8, as shown, andlsimilarly secured by" it pedestals to the tank, 'for rigidconnection vl"Valve 6 is preferably provided 'W' ha annular packing lll'for makin 'a tiv t'clos ing engagement against` the va veiseat Wife lowered, vas in Fig. 2. The packing rin'gf'jl is so mounted inl the valve that it Will sea directly uponthe inner edge of the she1l2 y so that `it' the. outlet conduit 4 should broken, the closing of the valve will reina-1 valve lugs-7 by a cross'pinlexteridi through theA widened diamond .shapedI ter niinals '16 and aringslot 17 thereon/pro viding 'fora limited range'of twisting move ment therein, as the-stem is .rotated to look ing and unlocking position. t

The valve 6 4is itself prevented `:trom ro w tion,` while allowing' forl free upwardV a w V1 tothe valve 1n any suitable Way. As sliouvvnl,` they are intemral 'extensions of the outer semi-circular c ampinoring 14C surroundin vthe valve 6 and tightly clamping thefpaellllw ing 14 thereto' by bolts 14"'. 'Valvef 6 is prof vided with drainage holes 141C forsurplii`A` liquid,in emptying. Guides 18 embrace t'ili vertical standards 13 at each side,with sdf iicient clearance to allow for free'upward 95 and downward movement under action-offthe raising and lowering stem7. v "f As shown in Fig. 1,-said stem, in its K' tbreadedrterminal portion 19,v providedv` a squared .top 20, for' application yof wrenrfh.. The threaded portionis 1 engaged,A by a; nut 21mounted ina cross plate orbearf' e ing 22, connected with the coping fra1ne'f23,"

v`the nut :having a turning 'handled or wheel 21, f B v `this means, thestem' 7 may be raised or' lowered with relationfto The Operating 'hels normallytclosedbl a coping 25 pivoted vat 26, and;mimbre.'`VA

J being locked by a padlock or similar-.meansilf at theotlier side, as at 27. By Such arrangi" ment, the coping may be opened to permit access to the wheel for adjustment, which is protected from unauthorized operation by the means shown.

In the operation of outlet valves in tank cars of the general type disclosed, there is usually present a variation between the top and bottom portions of the shell ot' the tank, due to expansion and contraction, or the strains of traffic, etc. Such variation .is afrequent cause of leakage where the 'yalve cbntrollin the outlet is operated by the stem having its full length intervene between the valve and a controlling or locking element therefor located at the top of the car.

l.In my present invention, I avoid such ob jection by locatingr the controlling element for holding the stem 'of the valve andr the valve itself, especially in lowered sealingr` position, by means of. a construction located' approximately adjacent to the valve itself, and so connected with its seat as to provlde a Vpracticallyrigid mounting, independent of the variations above referred to. F or such purpose, valve stem is provided with an abutment or shoulder 28, of any suitable form, as diamond shape in cross section, the laterally extending portions of the abut# ment heilig capable of free insertion through a corresponding opening or recess` 29 downf through the upper cross members 9 and l-j ofthe bracket support 8. The upper edges 31 of abutment 28 slope downwardly vand outwardly, providingwedging faces, giving,r downward pressure upon rotation. The lower end ot stein 7 is similarly shaped by the laterally extending diamond shaped terminal 1G above referred to. rl`he transverse member 10 is also provided with a suitably shaped opening 30 for insertion and removal of the stem in assembling it with the valve 6.

In operation, assuming; the valve open, with abutment 28 extending upwardly into p the clearance recess 29, an operation of the handy wheel 24 and nut 2l will lower the valve 6 upon its s at, suflicient tightening movement thereof being effected by the nut. In such position, the abutment 2S is lowered below the recess 29, and by proper reverse' movement ot' the nut, the frictional en ,ragcment with the threads 19 will operate is positively locked by the shouldered engagement between the abutment and the frame, so that the stem is not subject to any variation from its normal contour,` of the upper portion ofthe tank car 2. 1

In case of any undesired slippage, or fai.T

atraco@ l ure to positively rotate the' stem in the manner suggested, a wrench can be applied to the terminal 20 for independentrotation of the stem and seat of the valve 6. When it is desired to open the valve, the operation above described is reversed, abutment 28 first being brought into register with recess 29 and then ralsed by the thread and nut in the usual way.

ln the construction shownin Figs. 10, l1 and 12, l employ a sleeve 32 having an operating hand wheel 24, mounted in substantially the same manner as above described as to stem 7, but extending downwardly around the stem and having thread- 4ed engagementwith it, as indicated at 33.

The lower end 34 of sleeve 32 in such construction constitutes a nut journalled within the upwardly extending projection 35 ofa frame 8, belng provided at its lower end with a terminal abutment 36 and at its upper portion'with a clampingr collar 37. These two elements operate to maintain the nut fixedly against vertical movement in its bearing` 35, so as to positively .raise and lower the vstern 7 in the same manner as above described.l In such construction, the locking abutment 28 is shown in its raised position, having been lifted by action of the threaded sleeve to raise the valve from its seat. Iins 3S limit rotation of abutment- 28 to registering position.

With either construction, the .positive raising and lowering of the valve is easily and accurately, effected. The valve when lowered will be positively held to its seat independent of the objectionabley vibrations, variations, etc. above referredto. The advantages ot' the invention will be readily understood and appreciated by all those familiar with this class o'mechanism. l't overcomes the possibility ot' leakage due to the causes noted, and enables the use of an internal valve, overcoming the danger otloss of the contents of the tank car where a valve is mounted in the outlet conduit 4;. The latter, as is well known, is frequently broken or lost, due to knocks and strains of trafiic.

` The invention may be variously changed or modified 'in detail construction by the skilled mechanic, but all such changes are' to be considered as within the scope of the following claims.

A valve for tank cars and the like provided with an extended rotatable operating stein having a lateral locking key abutment and a holding frame therefor located closelyy adJace'nt to the valve provided with a trans-f verse opening .tor passage of the locking key abutment.
